is the 30 year (ZB) a short ?

during all these doom threads it may be time to think about trading and plan where the next chance could be.
I have a short ZB on my list:
1) It went higher during the market turmoil but by far not as strong as one would expect. This means relative weekness
2) Emerging markets like china may need to raise money and sell US-Bonds to cover their own troubles.
